I have very few positive things to say about "Jurassic Prey". Like most dinosaur flicks from the last few years, it's neither a good movie nor a so-bad-it's-good movie. It probably isn't one of the absolute worst movies I've ever seen, but I'm fairly sure it is somewhere in the "bottom 100" I have watched. It is one of the worst of the prehistoric genre and should be avoided or watched with extremely minimal expectations and some hard liquor.
The cast is generally awful in uninteresting ways; there are in fact ways B-movies can save a poor script with colorful characters and/ or colorful character actors, and this movie doesn't attempt to give us anyone to really care or root for, let alone laugh at. The visual effects are hilariously bad, however I cannot condemn them to the degree some reviewers have. Yes, the puppetry and stop-motion is not commendable, but I still prefer it over most of the cheap CGI in low budget dino-flicks the last few years. In fact I was bothered far more by other effects, such as the bad digital flames, blood, and gun flares among other poorly-executed shots.
If there were at least a few more redeeming elements (better gore, characters, and script for starters), I'd elevate my rating to a "3" or "4"; as it is, a "2" feels fairly generous.
